When I was an apprentice at Dowty we were sent to Stroud College to learn some specialist skills and complete an electronics project. We decided to build a tracking solar panel that followed the sun. For this we needed a framework to support our mocked up panel. So I temporarily joined the metal work class and watched the demonstration of lots of different types of welding. I also learnt how to braze using Oxy-Acetylene. I practiced this on the framework for the tracker.
More recently I attended an evening class at Chelsea College of Art and Design with some other beginner welders
where I built a giant flea sculpture using MIG welding.
After doing some research I bought a small DC TIG welder from R-Tech Welding
who I also use for welding supplies
. The reason for picking this is that it’s has less sparks so is safer for my small workshop and can be used on a wide variety of sizes of steel. I did not need to use the welder in a lot of different places so transporting the argon tank is not an issue. I have used this welder for variety welding projects in my workshop shed which you can see listed below. If you use MIG or TIG then I can definitely recommend getting a large refillable gas canister (in my case argon) as the small disposable canisters will run out quickly and it will become expensive very quickly. I found that even for a quick project such as my Obelisks that required multiple canisters.
Bespoke furniture maker Jamie Hubbard asked on twitter the other day if anyone knew the name of the following screw which he’d dug out of an old car light fitting. I thought they looked very like the screws you get
